Subject: [PATCH] fpdoc: new utility to generate a PDF with the footprints used
 in a project

- fab/pos2fab: can be called with "do", to read .pos and .cmp file
- fpd2pdf/fpd2pdf: added syntax extension file.fpd:package to allow
  selection of a single package
- fpd2pdf/fpdoc: generate a PDF with the footprints used in a specific
  project
